The external combustion hopper that is used for low temp fuel
The present invention relates to a kind of automobile-external combustion hopper that is used for low temp fuel, said low temp fuel is in one and is positioned within this external combustion hopper in-to-in fuel tank.
By US6347719B1 a kind of external combustion hopper that is used for low temp fuel is disclosed for example.This known external combustion hopper is designed to advection layer-flying body with lightweight construction.This external combustion hopper is designed to spherical, and is formed by compound wall.Be provided with one in the inboard with this external combustion hopper is that spherical metallic walls is as fuel tank with being separated by equally.Inboard wall and multilayer outer wall interconnect through welding, more precisely are on two opposed radials of container, obtain composite structure thus, also just say that the external combustion hopper is not a self-supporting.Such external combustion hopper is because its chondritic and bulky, and can only difficulty ground and under the situation of a large amount of usage space of loss, just can be installed in the automobile.Another shortcoming of this known external combustion hopper is a processing difficulties, and particularly external combustion hopper and fuel tank only can be made together, and before single part links together, has very big fragility.
DE10163029A1 discloses a kind of round barrel shape High Pressure Hydrogen gas tank, and wherein inboard polyethylene-lined centers on outer twister, and this twister should prevent bulge effect.In addition, the inboard of lining also is provided with hydrogen obstruction position (Wasserstoffbarrierelage).Such Fuel Tank is limited by space problem equally, especially in vehicle structure.
Strengthening measure for the large-area container that occurs the cripling depression easily is very firm mostly; Thick wooden partition reinforcement is owing to use a lot of webs or dividing plate in low temperature-fuel tank; Both caused the process technology that expends, and also caused the interconnection technique that expends, and finally cause high weight.This is to prevent because the depression of the external combustion hopper that bar pressure causes; The fuel tank strengthening measure of web through welding can not be used for low temperature-outer fuel box container; Because web does not allow the placement of fuel tank; And, thereby and there is not the position to be used for this interior reinforcement because must between fuel tank and external combustion hopper, have multilayer for heat insulation.In addition, do not allow to exist hot penetration outside between Fuel Tank and the fuel tank.
Technical matters to be solved by this invention is to create a kind of external combustion hopper, and the preferred self-supporting of this external combustion hopper is used for the low temp fuel of automotive use, especially compact automobile, and like car, this external combustion hopper also can be installed under the situation of restriction simply.Another important viewpoint is that this external combustion hopper simply mode is made, for example also can be automatically by means of robot assembling (welding).In addition, this external combustion hopper should only have less weight.
Solve thus by this technical matters of the present invention, that is, the external combustion hopper is designed to flat structure, especially is designed to parallelepiped, and the flat side of external combustion hopper is designed to sandwich structure at least partly, or strengthens with sandwich plate.

Another form of implementation is characterised in that, the sandwich plate that is bonded on the flat sidewall of external combustion hopper has the sandwich plate of top belt, yet does not have bottom tape, and wherein, the sidewall of external combustion hopper is as bottom tape, and is the part of sandwich plate.
If the top belt of sandwich plate at least, preferred top belt all is connected through weld seam with the sidewall of its edge with the external combustion hopper with bottom tape, then can obviously improve the rigidity of Fuel Tank.
If the sidewall of external combustion hopper is in forming process; Especially in the cold forming process process, as in drawing process, making, then the preferred side on the edge of of sandwich plate extends to a sclerosis of a sidewall; Especially the fringe region of flow harden, and in that and this fringe region welding.
One outer container can have good especially space availability ratio thus; That is, sidewall is equipped with outwardly peripheral bead or protuberance in all zones of ring, and; Sandwich plate extends to this marginal rise at least and welds with the sidewall of its top belt and external combustion hopper at least at that; Wherein, the top belt of sandwich plate preferably is positioned at same plane with peripheral bead, just its highest zone.This peripheral bead can have special advantage and be used to hold the adapter between external combustion hopper and fuel tank, and needn't therefore increase the height of Fuel Tank.
By a kind of preferred form of implementation, sandwich plate extend to always one with external combustion hopper adjacent side panels, like body side, and captive joint with it, for example tighten, the external combustion hopper also helps to strengthen adjacent vehicle body zone thus.
As the extra safety method that prevents that sandwich plate from coming off from the sidewall of external combustion hopper; Be fixed with the T-screw that extends perpendicular to sidewall on the sidewall of Fuel Tank with the sandwich plate reinforcement outside; These screws extend through sandwich plate, and this sandwich plate is by means of tightening the T-screw retention outside on the Fuel Tank.
Owing to weld the warpage that causes, the weld seam that connects sandwich plate and external combustion hopper is preferably designed for the weld seam of segmentation in order to reduce as far as possible.
In practice, in big zone, can preferably withstand external pressure by external combustion hopper of the present invention.Therefore, the external combustion hopper advantageously has between the height 100 to 500mm, preferably 200 and 350mm between, and length or width 500 and 1400mm between, preferably 700 and 1000mm between.
The thickness of sandwich plate preferably 5 and 20mm between change.
A kind ofly optimize being characterized as of the form of implementation that adapts to M curve, sandwich plate have one have an opposite edges regional seal supporting core, the especially zone line of honeycomb structure shape core.
For avoiding the rigidity sudden change at the periphery of sandwich plate, sandwich plate in height reduces until periphery in its peripheral edge margin gradually, and preferably in this peripheral edge margin supporting core is not set.
For the sidewall that guarantees sandwich plate and external combustion hopper bonds intactly; The contact surface of sandwich plate and external combustion hopper has air exhaust passage; Be used to improve adhesive-hardening and exhaust, said exhaust passage is formed by rib on the sidewall of passage in the tack coat and/or external combustion hopper and/or the hole in the sandwich plate.
Sandwich plate preferably guides until one and is arranged on ancillary system housing external combustion hopper next door, that be used for Fuel Tank assembly (valve etc.), and captives joint with this ancillary system housing, as is threaded, and thus, the reinforcing of the external Fuel Tank of ancillary system housing is favourable.
Be save weight, the top belt and the bottom tape of the not only sidewall of external combustion hopper, and sandwich plate are all advantageously formed by aluminum or aluminum alloy, and wherein, supporting core is also preferably formed by aluminum or aluminum alloy.
The fringe region of external combustion hopper and narrow edge regions preferably do not have the interlayer reinforcement.
Next specify the present invention according to a plurality of forms of implementation that schematically illustrate in the accompanying drawings.

Fig. 5 to 8 shows the different distortion of the peripheral edge margin formation of sandwich plate, and the bonded assembly cross-sectional plane of sandwich plate and external combustion hopper;
Fig. 9 at length shows form of implementation shown in Figure 6 once more,
Figure 10 shows another distortion similar and shown in Figure 9.
Be used to store low temp fuel at the fuel tanks of automobile shown in Fig. 1 and 21.For avoiding hot penetration not form with external combustion hopper 2 direct coupled fuel tank 3, this fuel tank is used to hold low temp fuel to this Fuel Tank by external combustion hopper 2 and.
External combustion hopper 2 is configured to self-supporting; And start from the weight reason preferably by aluminium sheet by two; That is to say the pull and stretch slab processed by aluminum alloy or Fuel Tank half one 2 ', 2 that produces by other the slab of method moulding " form, said two Fuel Tank half ones interconnect with weld seam 4.External combustion hopper 2 has the shape of rectangular parallelepiped.The height 5 100 and 500mm between, preferably 200 and 350mm between, width 6 and length 7 500 and 1400mm between, preferably 700 and 1000mm between.8 because deep-drawing technique produces flow harden in round edge edge zone.
The top side of Fuel Tank 2 and bottom side just are bonded with a sandwich plate 9 respectively on the sidewall 13 of the maximum of external combustion hopper 2 outside, and this sandwich plate is preferably designed for aluminium honeycomb structure shape sandwich plate.In honeycomb structure shape sandwich plate, be used for heat insulationly by the honeycomb structure closed air, this has just improved fireproofness.As shown in Figure 3, this sandwich plate 9 has a leak free honeycomb structure device at zone line or middle section 10, so that withstand better in zone line 10 because air pressure strengthens cripling or the depression load (Beulbelastung) that occurs.Reach the thickness 11 that minimizes sandwich plate 9 thus.
Each sandwich plate 9 directly is bonded on the sidewall 13 of external combustion hopper 2 by means of tack coat 14 with its bottom tape 12.As bonding material, high shear strength is proved to be actv. with the anti-two component-adhesive agents that divest intensity (Schaelfestigkeit).Also can use adhesive film, because can reach high anti-peel force (Schaelkraeft) equally through this adhesive film.In order to guarantee adhesive-hardening in working order and the gas in order to get rid of in this generation from tack coat 14, sandwich plate is provided with exhaust passage 15.This passage 15 also can convex to form through the hole in the sandwich plate 9 or through the rib shape on the sidewall 13 of external combustion hopper.
As shown in Figure 5; The peripheral edge margin 16 of sandwich plate 9 is configured to wedge shape, that is to say, top belt 13 transits to bottom tape 12; Wherein, There is not honeycomb structure in fringe region 16 in this attenuation, therefore, avoids or reduce rigidity too big from the transition of sandwich plate 9 to sidewall 13 (its fringe region 8 just) suddenling change.Sandwich plate 9 preferably has top belt and bottom tape 17,12, and said top belt and bottom tape are made of aluminum, are preferably processed by aluminum alloy.
Not only the top belt 17, and bottom tape 12 outside in the fringe region 8 of the sidewall 13 of Fuel Tank 2 with the sandwich plate welding, wherein, weld seam 8 or extend discontinuously, or be embodied as the weld seam of interruption for the danger that reduces to be out of shape.
Fig. 6 and Fig. 9 show in detail especially preferred form of implementation in.By this distortion, the sidewall 13 of external combustion hopper 2 has outwardly a peripheral bead 19 (Randsicke) or an arch configuration.At this, the bottom tape 12 of sandwich plate 9 and sidewall 13 welding of top belt 17 with external combustion hopper 2 more precisely are the fringe regions 8 at flow harden.Through peripheral bead 19 inside of Fuel Tank 2 outside, a position is created for pipe 20 (Verrohrung) in the inside that just is configured to evacuated space outside between Fuel Tank 2 and the fuel tank 3.Available Fuel Tank height 5 can be owing to this peripheral bead 19 increase, and especially because the peripheral bead 19 of encircling Zhou Yanshen at sidewall 13 forms depression on said sidewall 13, this depression is used to hold sandwich plate 9.Therefore at this, the fringe region 16 of sandwich plate 9 also can be designed to not have honeycomb structure, avoids or reduces the rigidity sudden change in the fringe region.
Other advantage of peripheral bead 19 is, that is, because peripheral bead has obtained two pull and stretch parts 2 ', 2 of external combustion hopper 2 " better shape and size stability.
By form of implementation shown in Figure 7 is a Fuel Tank assembly; Like valve, be used to hold the ancillary system housing 21 of Fuel Tank 1, this ancillary system housing self is designed to hard housing; And be adjacent to be provided with external combustion hopper 2; And for example 22 be connected with sandwich plate 9 ground end regions through being threaded, thus, ancillary system housing 21 also helps external combustion hopper 2 ground and strengthens.
External combustion hopper 2 is designed to the reinforcement in vehicle body zone in distortion shown in Figure 8, wherein, vehicle body steel plate 23 is connected with the fringe region of the sandwich plate 9 of the fringe region that stretches out in external combustion hopper 28, for example through being threaded 22.
Can know T-bolt 24 by Fig. 8, this T-is bolted on the sidewall 13 of external combustion hopper 2, and stretches into sandwich plate 9 through groove 25.Sandwich plate 9 adds on the sidewall 13 that packing ring is fixed on external combustion hopper 2 by means of being tightened in nut 26 on this T-bolt 24, therefore prevents that reliably sandwich plate 9 from peeling off and causing the depression of sidewall 13 from sidewall 13.
Figure 10 shows a kind of distortion, and wherein, sandwich plate 9 only has top belt 17.In this case, honeycomb structure directly, that is to say does not have bottom tape 12, is bonded on the sidewall 13, realizes thus, balance is because the accuracy of manufacture of sidewall 13 that produce, external combustion hopper 2 such as pull and stretch, like out-of-flat.In this case, sidewall 13 itself forms bottom tape, so sidewall 13 is integrated in the sandwich plate 9, and just sidewall itself can be regarded as sandwich plate.Can know that by figure not only in the distortion of pressing Fig. 9, and in the distortion of pressing Figure 10, top belt 17 almost on even keel is connected on the peripheral bead 19.
Another advantage of distortion shown in Figure 10 is, can pass through the foraminate honeycomb structure exhaust of design.Bending-resistance-the moment that is exactly specified weight in addition is bigger, because bigger (the increase value is the one-tenth-value thickness 1/10 of bottom tape 17) that the height of honeycomb structure can be measured.In addition, also realized save weight (because not having bottom tape) thus.(just the top belt of sandwich plate 9 and bottom tape must be welded with fringe region 8 simultaneously) was simpler when only the manufacturing of the weld seam 18 between the fringe region 8 of top belt 17 and external combustion hopper 2 was also than two allegros.
Handle and be pressed on occurring easily on cripling or the sunk surface of sidewall 13 at the sandwich plate that applies bonding material on the sidewall that will strengthen 13 and will cut out 9; Can carry out simultaneously as coating bonding material in the vehicle body production in enormous quantities, just full automaticity ground carries out by means of robot or with adhesive film.Equally, sandwich plate 9 also can carry out by means of robot with the welding of the sidewall 13 of external combustion hopper 2.
The present invention is not limited only to various form of implementation shown in the drawings, but can revise in every respect, and with solving technical matters to be solved by this invention.The external combustion hopper also can have cylindrical shape, yet its height much smaller than diameter, wherein, disc covers with a sandwich plate, or shown in figure 10, is designed to sandwich plate.Obtain a flat structure thus equally.
